Answer:
The 99% confidence interval is
Step-by-step explanation:
From the question we are told that
The sample size is n = 514
The sample proportion is
From the question we are told the confidence level is 99% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of is
Generally the margin of error is mathematically represented as
=>
=>
Generally 99% confidence interval is mathematically represented as
=>
That line that is made out of angles 1 and 2 is straight. What we know about straight lines is that they're 180°. This means that ∠1 and ∠2 are supplementary, adding up to 180°.
∠1 + ∠2 = 180
∠1 = (x + 81)
∠2 = (2x)
(x + 81) + 2x = 180
3x + 81 = 180
3x = 99
x = 33
The answer is x = 33.
